1.3 Essay Questions
1) Microeconomists and macroeconomists take some common approaches to studying economic
problems, but there are also important differences in what these two types of economists do.
Discuss.
Answer: At one time macro and micro were approaches in very different ways, but since the
1970s, macroeconomists have adopted an approach in which they build macroeconomic models
from microeconomic principles. Thus, the methodological approaches in micro and macro have
become more similar over time. However, microeconomists and macroeconomists study very
different problems. In microeconomics the focus is on individual economic actors and markets,
and how they behave. However, in macroeconomics the focus is on large economic units —
countries, governments, central banks — and how they behave.
LO: 1.1: State the two focuses of study in macroeconomics, the key differences between
microeconomics and macroeconomics, and the similarities between microeconomics
Difficulty: easy
Classification: concept
AACSB: analytical thinking
2) Macroeconomists are interested in two types of phenomena: economic growth and business
cycles. Explain how macroeconomists manipulate economic data in order to study these two
problems.
Answer: A typical approach macroeconomists take is to separate the trend component from the
business cycle component in macroeconomic time series data. For example, suppose that we are
interested in the trend and cyclical components of real GDP per capita. First, we would take the
natural logarithm of the time series. Then, we would fit a trend to the natural logarithm, and
measure the cyclical component of real GDP per capita as the deviation of the actual time series
from the trend. This then gives us some idea of the trend growth component and the business
cycle component of real GDP per capita that we want to understand.

domestic product in the United States from 1900 to 1914.

3) Explain why macroeconomists like to build models.
Answer: In macroeconomics, in contrast to the natural sciences, for example, it is difficult or
impossible to run experiments to test theories. As an alternative, macroeconomists find it useful
to construct artificial apparatuses — models — on which they can run artificial experiments. The
basic idea is to build the model, fit it to the data in some sense, and then ask how the model
responds to changes that mimic the real-world experiments we would actually like to run.
LO: 1.3: Explain why models are useful in macroeconomics.
Difficulty: moderate
Classification: application
AACSB: analytical thinking
4) Why do macroeconomists build models based on microeconomic principles? Discuss.
Answer: In part macroeconomists are interested in understanding the consequences of changes
in government policy. But, when government policy changes, the behavior of individuals
changes in response to the policy. Therefore, we cannot accurately predict the results of a policy
change just from looking at historical macroeconomic relationships. That is, the Lucas critique
comes into play. If we build up macroeconomic models from microeconomic behavior, we have
the structure we need to accurately predict the results of changes in policy.
LO: 1.4: Discuss how microeconomic principles are important in constructing useful
macroeconomic models.
Difficulty: difficult
Classification: application
AACSB: application of knowledge
5) What do macroeconomists disagree about, and on what issues do they tend to agree? Explain.
Answer: Macroeconomists tend to disagree about the causes of business cycles. For example,
Keynesian economists tend to think that business cycles result from the stickiness in wages and
prices, or from coordination failures, and they think that government intervention to smooth
business cycles is a good idea. However, real business cycle theorists think that business cycles
are caused by aggregate shocks to productivity, and these macroeconomists therefore think that
government intervention to smooth business cycles can at best make things worse. But,
macroeconomists tend to agree about what models are useful in studying economic growth, and
about the causes of long run growth. For example, the Solow growth model is a common
approach to studying economic growth, which predicts that long run improvement in standards
of living comes from technological change.

6) What is the role of unemployment in a well-functioning economy?
Answer: Unemployment is obviously painful for the individuals involved. An unemployed
person uses up time and effort with no compensation, in the hopes of gaining employment, and
could be experiencing economic hardship in the process. But, for society as a whole,
unemployment is a necessary evil. Unemployed workers are seeking matches with firms which
have job vacancies, and those unemployed workers are quite diverse, as are the job vacancies, in
terms of skill requirements. It takes time for society to obtain good matches between workers and
jobs, which make the aggregate economy more productive in the long run. Thus, unemployment
actually can help efficiency, and implies that an economy can yield benefits for all.

7) Are tax cuts necessarily a good thing for the economy as a whole? Explain.
Answer: There are conditions under which tax cuts have no effect at all. The Ricardian
equivalence theorem says that there are conditions under which consumers who get tax cuts
receive no net gain in their wealth from a tax cut, and therefore do not alter their spending. As a
result, the tax cut will not matter for prices, quantities, or economic welfare. A consumer
understands that, when he or she receives a tax cut, that the government must fund the cut
through borrowing, and that the government debt must be paid off with future taxes. The loss in
wealth from future taxes just offsets the gain in wealth from the current tax cut.

8) Describe two key relationships between inflation and other economic variables, and explain
their importance.
Answer: The key relationships are the Phillips curve and the Fisher relation. The Phillips curve
is a positive relationship between inflation and the deviation of aggregate output from trend, and
the Fisher relation is a positive relationship between the inflation and the nominal interest rate.
The Phillips curve might suggest that a central bank can increase inflation by reducing output,
perhaps by lowering the nominal interest rate. Neo-Fisherism, however, suggests that increasing
the nominal interest rate causes inflation to rise, through the Fisher relation.

9) Explain what the Beveridge curve is, and why it is important.
Answer: The Beveridge curve is the observed negative relationship observed between the
vacancy rate — job openings as a percentage of job openings plus employment — and the
unemployment rate. The Beveridge curve was observed to shift during the 2008-2009 recession,
and this shift has persisted over time. This shift is perhaps an indication of mismatch in the U.S.
labor market — a mismatch between the skills of unemployed workers and the skills needed to
fill job openings.

10) Explain the role of interest rate spreads in the financial crisis and recession of 2008-2009.
Answer: The recession of 2008-2009 is usually attributed to the financial crisis, which
culminated in the financial disruption in the fall of 2008. The financial crisis created substantial
uncertainty, which we can characterize as a situation of asymmetric information. In financial
markets, asymmetric information can lead to default premia on assets, for example on corporate
debt. Then if we look at the difference between interest rates on corporate debt of different
riskiness, such "spreads" should increase in times when asymmetric information frictions
increase. In particular, during the financial crisis, we observed increases in these spreads.
Increases in spreads also occurred in previous recessions, but the increase in spreads during the
financial crisis and the Great Depression were particularly large.
